8. Symmetry
a. Performance Check
(1) Position controls as listed in (a) through (d) below:
RANGE switch to X.1.
(a)
CHANNEL A function switch to SQUARE.
(b)
CHANNEL AMPLITUDE control to midrange.
(c)
FREQUENCY dial to 10.
(d)
(2) Connect calibrator to FREQUENCY CONTROL (rear panel).
CAUTION
Voltage must be limited to between +0.3 and -15 V. Voltage
outside this range will damage TI. Do not use standby/reset
position of calibrator.
(3) Adjust calibrator output to 0.3 V.
(4) Connect frequency counter to TI CHANNEL A OUTPUT.
NOTE
For convenience (because of long time interval of TI signal),
obtain initial settings for start and stop channels with TI
RANGE switch turned to X100; then, set RANGE switch to
X.1 and continue with performance check.
